The video shows the London underground train leaving, but not long after it passes, the stroller — pushed by a gust of wind — makes its way from the subway staircase out onto the track.

The baby's parents apparently turned away for a moment as the stroller started to move. A woman, presumably the mother, jumped onto the tracks to lift the baby up, and an onlooker helped pull the child to safety.

Investigators are hoping to identify the couple in order to ensure that the baby did not sustain any injuries, according to FoxNews.
